Who proved that matter is made up of particles?
In the early 1800s, the scientist John Dalton noticed that chemical substances seemed to combine and break down into other substances by weight in proportions that suggested that each chemical element is ultimately made up of tiny indivisible particles of consistent weight.
Is it true that matter is made up of particles?
All matter is composed of tiny indivisible particles too small to see. These particles do not share the properties of the material they make up. There is nothing in the space between the particles that make up matter. The particles which make up matter are in constant motion in all physical states.

Who suggested the idea of particles?
DemocritusMore than 2000 years ago in Greece, a philosopher named Democritus suggested that matter is made up of tiny particles too small to be seen. He thought that if you kept cutting a substance into smaller and smaller pieces, you would eventually come to the smallest possible particles—the building blocks of matter.
What is always true about particles that make up matter?
C The particles that make up all matter are constantly in motion.
What's the particle theory of matter?
The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
Which statement about the particle theory of matter is true?
The correct answer is A. According to the particle theory of matter, all particles of matter move constantly. The particles in solid objects move even though we cannot see it. Since they are tightly packed together, they are vibrating in place.
Why are particles observed?
The particle nature of matter is known and used to our advantage. Particles are observed routinely due to radioactivity. Photographic film reveals tracks of charged particles emitted by radioactive materials. Cloud- and bubble chambers reveal the emitted particles of radioactive processes.

What is Rutherford's famous gold leaf experiment?
He concluded from it that atoms must be mostly “empty space” with their mass concentrated in a tiny space.
How do protons help cancer?
The idea behind this is to accelerate protons to low energies where they penetrate the human body and leave most of their energy (acquired during acceleration) at a certain depth in the tissue. The important feature of protons is that there is a narrow region (in terms of depth in the human body) where they leave most of their energy and therefore destroy tissue mostly there. This is a clear advantage compared to treatment with photons (X-rays or gamma rays) which cause more 'collateral damage'.
How are photons detected?
In this example, the photons (particles) leaving the patient's body can't be seen directly but are detected by means of a dedicated apparatus where they produce a tiny amount of light or leave an electrical signal. This is then digitized and stored for further processing in a computer.

Students are introduced to the idea that matter is made up of tiny particles called atoms and molecules.
What is matter made of?
Matter on Earth is in the form of solid, liquid, or gas. Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don’t move past one another. In a liquid, the particles are attracted to each other ...
Why can a bottle be squeezed with the lid on?
Explain that with the lid on, the bottle can still be squeezed because gas molecules have a lot of space between them and can be compressed.
How to squeeze a bottle of water?
Hold the bottle and squeeze it until you can’t squeeze it any further.
Why do scientists use models?
Scientists use models to try to understand the behavior of atoms and molecules and to help explain the properties of matter. Note: Even though atoms and molecules are different, for the purpose of this lesson, they both will be represented in the same way as a circle or sphere.
What happens to particles in a liquid?
In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another.
Why do students use models in science?
Students will use the model to describe the differences in attraction among the particles of a solid, liquid, and gas. Finally, students will use their models of solids, liquids, and gases to explain their observations in the lesson.
